Express-子域路由无法正常工作？

Question

I have been looking for solutions for a couple days now trying to google it and all and now i am here. I am trying to setup subdomains for my app using express-subdomain package. However in the example below the app ALWAYS returns app.get route and skips the other subdomain routes specified. I have also in turn added the hosts file url so i know that should not be the issue.

It must be in my code for some reason it always ends up displaying Detect Region route even when accessing oce.localhost:3000.

Please help me :)

Server.js

var subdomain = require('express-subdomain');
var express = require('express');
var app = express();

// Region routes
var router = express.Router();
var na = require('./routes/region/na.js');
var oce = require('./routes/region/oce.js');

router.use(subdomain('na.localhost', na));
router.use(subdomain('oce.localhost', oce));

app.get('/', function(req, res) {
    res.send('Detect Region and send to correct subdomain!');
});

app.listen(3000);

routes/region/oce.js

var
  express = require('express'),
  router = express.Router();

router.get('/', function(req, res) {
    res.send('Your are in OCE Region!');
});

module.exports = router;

And na.js is pretty much the name as oce.js

Cheers

You are setting your subdomains in the router variable but you don't tell your app to use it.

You have to do that :

app.use(router);

You put it in place of your current app.get .

Edit

You could also put your app.get after the app.use(router) so that it will act as a default route. (When you are neither on oce or na , it will use it)

Edit after some testing

Alright I've been able to make it work using express-vhost . I just updated your server.js like so :

 var subdomain = require('express-vhost'); var express = require('express'); var app = express(); // Region routes var router = express.Router(); var na = require('./routes/region/na.js'); var oce = require('./routes/region/oce.js'); subdomain.register('na.localhost', na) subdomain.register('oce.localhost', oce) app.use(subdomain.vhost(app.enabled('trust proxy'))); app.get('/', function(req, res) { res.send('Detect Region and send to correct subdomain!'); }); app.listen(3000);
